初二英语动词不定式知识点
初二英语动词不定式有动词特征和非动词特征,英语动词不定式的特征在汉语句式中得到充分体现。以下是小编给你推荐的初二英语动词不定式知识点归纳,希望对你有帮助!
动词不定式知识点:不定式结构作主语get contact with his family in Taiwan made him extremely happy since they separated more than 40 years ago.
finish that task in such a short time is really a challenge.
在上述情况下,如果不定式较长,显得头重脚轻,则可由代词让作形式主语(形式主语it不可由that或this等其他代词代替),而将不定式放到后面。如:
made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago. admitted that it is always difficult for him to be on time.
不定式结构所表示的动作是谁做的,即不定式的逻辑主语,通常可以通过for sb. to do sth. 结构表达: is quite important for us to read good books during a general review. is not difficult fot those talented students to pass the exam. 在某些形容词(如careless,clever,considerate,foolish,good,impolite,kind, naughty,nice,silly,stupid等)作表语时,不定式后可以加of来引导出其逻辑主语: is very kind of you to tell me the truth. is stupid of him to do such a silly thing.
动词不定式知识点:不定式作宾语不定式作宾语 不定式作宾语有两种:一种是及物动词后直接跟带to的不定式, 另一种是“及物动词+疑问词+带to的不定式。
及物动词+带to的不定式结构: 只能跟动词不定式的动词,常见的有: afford, agree, aim, appear, ask, believe, care,claim,decide demand, desire, determine, expect, fail, happen, hesitate, hope, intend, learn, long, manage, offer, pretend, promise, prepare, refuse, seek, swear, undertake,want, wish等。
managed to solve the complicated problem. stranger offered to show me the way. . Smith undertook to build a new plant in South Africa.
动词+疑问代(副)词+不定式: 这类动词常见的有advise, decide, find out, forget, inquire, know, learn, see, regard, remember, teach, tell, understand, wonder等。常见的疑问代(副)词有: what, when, where, which, how, whether等。
does not know when to start. can decide whether to continue or to stop. 3.I will show you how to deal with it.
有时,不定式可由it代替,而把不定式放到后面去。这可以用这一结构表达:动词(如find, think,consider,feel等)+it+ 形容词+不定式。 considers it necessary to make friends with him. find it difficult to finish all the homework before 9 o’clock.
动词不定式知识点:不定式做表语不定式做表语 一种情况为主语是不定式(表示条件);表语也是不定式(表示结果):
see is to work means to earn a living.
另一种情况为主语是以aim,duty,hope, idea,job, plan,problem, purpose,thing,wish等名词为中心的短语,或以what引导的名词性从句,不定式表语对主语起补充说明作用;例如: aim is to study abroad in the near future. most important thing is to negotiate with them about the price. I want to say is to forget all the unhappy experience.
动词不定式知识点:不定式作定语不定式作定语 不定式结构作名词词组修饰语主要有三种类型:
第一种,被修饰的'名词词组是不定式的逻辑宾语。例如: e was really nothing to fear. gave me an interesting book to read. 如果不定式是不及物动词,后面就得加相应的介词。例如: needs a friend to play with. girl has nothing to worry about. have a strict teacher to listen to. ough the film had been on for ten minutes, I still was not able to find a chair to sit on.第二种,被修饰的名词词组是不定式的逻辑主语;例如: you got a key to unlock the door? action to be taken is correct. e is nothing to be gained by pretending.第三种,被修饰的名词词组是不定式的同位结构。这类名词通常是表示企图、努力、倾向、目的、愿望、is算、能力、意向等意义的名词:ability, attempt, effort, impulse, inclination,wish等。例如: daughter will make an even bigger effort to please her. 2.I have no wishto quarrel withyou. her of them had any inclination to do business with Mary.
动词不定式知识点:不定式作状语不定式作状语 不定式结构在句中作状语通常都能转换为限制性状语从句。例如作原因状语: are quite surprised to see the great changes taking place in the area. are quite surprised because they see the great changes taking place in the area. was lucky to arrive before dark. was lucky because he arrived before dark.
作目的状语: raised her voice to be heared better. raised her voice so that she could heard better. went via Heidelberg to miss the traffic jam. went via Heidelberg so that we could miss the traffic jam.
作结果状语: French football team played so successfully as to defeat the Brazilians. French football team played so successfully that they even defeated the Brazilians. got to the station only to be told the train had gone. got to the station and was told that the train had gone.
不带to的不定式的使用 动词不定式通常带to,但在有些搭配中不带to,在另一些搭配中可带to可不带to
